I renewed my subscription service for another year. I have a PC and two laptops. Zone alarm sent me the license key, which was accepted on the PC and one laptop. When i try to input it into the second laptop, it will not accept it. It says it is invalid. It should be noted that the new key is exactly the same as the one already in the laptop.

The laptop runs windows xp and zone alarm is version 7.0.483.0

I never upgraded beyond 7 because they discontinued the cookies/popup/mobile code control that I liked.

So any idea why my license key would be rejected?
